Syntheses of an α-D-Gal-(1→6)-β-D-Gal diglyceride, as lipase substrate

Two different routes were explored to afford 3-O-(6-O-α-d- galactopyranosyl-β-d-galactopyranosyl)-1,2-di-O-dodecanoyl-sn-glycerol. In the first one, the key step was the glycosylation of the 3-O-(2,3,4-tri-O- benzyl-β-d-galactopyranosyl)-1,2-O-isopropylid

O-Alkylierung am anomeren Zentrum, 4. 1-O-Alkylierung von D-Mannofuranose und D-Mannopyranose

From 1-O-metallated 2,3;5,6-di-O-isopropylidene-D-mannose (1) and strong alkylating agents (triflates) β-D-mannofuranosides were obtained, addition of crown ether resulted in α-D-mannofuranoside formation.From the 6-O-unprotected D-mannose 7 a similar ste

SYNTHESIS OF α- AND β-GLYCOPYRANOSIDES via 1-O-ALKYLATION

1-O-Alkylation of partly protected glucopyranose 1 and galactopyranose 13 led to a convenient, short term synthesis of β-glycosides and β-disaccharides 4a-d and 14.Glucopyranose 2 with a bulky protective group at O-6 yielded exclusively the α-anomer (isomaltoside derivative) 5.
